Sally Hanson is my #1 go to for Nail Stregthener, Hardener, Growth, Cuticle Ointment. Natural Nail Growth Activator works really well. I have been applying a coat in the morning and a coat at night after 2 weeks the results have really been effective. I am happy with the results and the polish itself, its shiny, smooth finish, light polish scent, no streaks. I hope you enjoy it as much as I do.
